高压直流输电线路电晕特性参数测量

The Parameter Measurements of Corona Characteristics of HVDC Transmission Lines

高压直流输电线路电晕特性参数包括地面离子流密度、合成电场强度、人或物体的充电电压、人体截获电流及线路电晕损失等。本文探讨了这些参数的测量方法、测量仪表及其影响测量准确度的因素。同时,对自动数据收集装置作一简单介绍。

The parameters of corona characteristics of HVDC Lines comprise the ion current density, total electric field, induced voltage on persons or objects, ion currents intercepted by persons, corona loss and so on. The methods of measurement and the instruments and the in fluenccs on the precision of the measurement are discussed. Meanwhile, the automatic digital acquisition device are also introduced.
